SCREEN AND GUARD FOR WINDOWS.

SPECIFICATION forming part of Letters Patent No. 766,262, dated August 2, 1904.

Application filed April 27, 1904;. Serial No. 205,088. (No model.)

To all whom it may concern..-

Be it known that I, ABNER JOHNSTON, a citizen of the United States, residing at Long Island City, in the county of Queens and State of New York, have invented certain new and useful Improvements in Screens and Guards for WVindows; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making apart of this specification, and to the letters of reference marked thereon.

The present invention has for its object to provide a guard attachment for windows in which the space between the sash when raised and window-sillwill be screened, and thereby prevent the papers or documents in an office from blowing out through the window when left open, and for other purposes to which a screen or guard may be found useful.

The invention consists inascreen and guard attachment for windows constructed substantially as shown in the drawings and hereinafter described and claimed.

Figure 1 of the drawings is a front elevation of a window, showing my improved screen and guard attachment applied thereto, showing the sash in a raised position and the screen and guard in use; Fig. 2, a perspective view showing the sash and the screen and guard closed; Fig. 3, a horizontal section taken on line 3 3 of Fig. 2; Fig. 4, a detail perspective view showing the means for attaching the screen and guard to the sill of the window.

In the accompanying drawings, A represents the frame of a window, andB O the upper and lower sash, respectively, which may be of any suitable construction, and to the lower rails of the sash O is secured the upper portion of the screen and guard, and the lower portion thereof is secured to the sill D of the window-frame. This screen and guard comprises in part the lazy-tonsE F, of any suitable material, two or more being used, as found desirable, to form a guard sufiicient to screen the opening between the sill and lower rail of the sash when the latter is raised to prevent bills, checks, and other papers upon the desk of an office from blowing out the window, two of these lazy-tongs only being shown in the present instance, which is deemed sufficient to illustrate the construction and application of my invention to a window. The lazy-tongs are pivoted at a to a plurality of horizontal guide-bars G, the extremity of ends of the bars engaging with upright grooved guides H upon the Window-frame.

Suitable blocks Z) are secured to the lower rail of the window-sash O, which have stationary pins 0 projecting therefrom, and a clamping-rail I has openings or holes f of sufficient size to loosely slip over the pins, as

shown more clearlyin Fig. 3 of the drawings,

to hold the ends of the rail in position on the rail of the sash.

A block (Z is secured to the rail of the sash, by which the rail I may be clamped to the sash through the medium of the screw-shank e of a knob J for convenience of lifting the sash or lowering the same.

The lower ends of the lazy-tongs E F are pivotally secured at g to suitable brackets K, said brackets being removably secured to the sill D of the window-frame, so that the guard and screen may be conveniently detached and removed from the window when circumstances require.

The construction of the brackets is shown in detail in Fig. 4 of the drawings and comprises substantially a right-angle plate with a transverse elongated slot 71- therein to engage a swinging or pivoted locking-pin 7:, said pins being secured to the sill of the window-frame.

When it is desired to remove the screen and guard, the knob J is unscrewed suflicient to allow the ends of the clamping-rail to be dis engaged from the pins 0 and the locking-pin '2: turned parallel or lengthwise with the slot h in the brackets K, when the screen and guard may be readily removed.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A screen and guard for windows, comprising a plurality of lazy-tongs, a plurality of horizontal guide-bars to which the lazytongs are 'pivoted, upright grooved guides upon the sides of the window-frame with which the ends of the guide-bars engage, suitable blocks secured to the lower rail of the sash and provided with projecting pins, a clamping-rail with which the upper ends of the lazy-tongs are pivoted, said clamping-rail having holes at its ends to engage the pins, a knob with screw-shanks for removably securing the clamping-rail to the sash, and means for removably connecting the screen and guard to the sill of the window, substantially as and for the purpose described.

2. A screen and guard for windows, comprising a plurality of lazy-tongs, a plurality of guide-bars to which the lazy-tongsare pivoted, upright grooved guides upon the sides of the window-frame with which the ends of the guidebars engage, a clamping-rail to which the upper ends of the lazy-tongs are pivoted, and means for detachably connecting said clamping-rail to the lower rail of the sash, and means for detachably connecting the lower end of the screen or guard to the sill of the window, consisting of pivoted locking-pins upon the sill and brackets with elongated slots with which the pins engage, said brackets-secured to the lower ends of the lazy-tongs substantially as and for the purpose specified.

In testimony whereof I aifix my signature in presence of two witnesses.

ABNER JOHNSTON.
